when using Linux/X11/Chrome on a SABRE Dual Lite board, screen tearing artifacts are encountered within the broswer. Following setup is used:
- Yocto Release 1.5, including
- Linux imx6dlsabresd 3.0.35-4.1.0+yocto+gbdde708 ( only one cpu activated )
- X.Org X Server 1.14.0
- Chrome Version 32.0.1664.3 ( 227606 ), with all GPU acceleration options enabled
When the Video Tearing test - YouTube is displayed inside the browser, tearing artifacts are visible. Tearing artifacts are also visible when swiping html5 pages.
If the same URL ( the YouTube tearing video ) is displayed on the SABRE Dual Lite board using an Android 4.2.2 image + Chrome 29.0.1547.59 no tearing artifacts are visible.
Is this behaviour known ? Are there any hints available, regarding the configuration of the subsystems preventing the tearing artifacts mentioned above ?
Any help would be highly appreciated.
